Hello BMW municipality, at this year’s oil change (20 km warm driven, oil filter unscrewed) the waste oil did not run off. I then ran the engine very briefly and the oil came out with quite a pressure. New filter screwed in, 3.8 liters of oil filled – the oil level is clearly visible on the glass. Engine started, the oil level sank very quickly in the glass and was not readable even after 1/2 hours of standstill. Of course, I don’t dare to move the mopped anymore without causing a capital damage. Something like that hasn’t happened to me in my entire screwdriver life. I’ve been changing oil for over 50 years with all my cars and motorcycles. The waste oil has always run unreservedly. Has any of you ever experienced similar things or can make a rhyme? I’m looking forward to every well-intentioned hint and I’m curious if anyone has ever told me something like that. Greetings Gerd.
